MasterM-Bus Converter

SHARE

The M-Bus is a bus optimized for the reading of measurement instruments like energy counters, hot and cold water counters, gas, pressure, sensors and actuators, etc. Nowadays, more and more manufacturers implement the M-Bus interface in their counters, making it the ideal basis for remote reading applications. Our M-Bus Master (M-Bus converter) is universal and simple M-Bus Master that can be connected up to 250 M-Bus devices. This device also convert M-Bus signal to RS232 or RS485 so basically you can integrate this device in your remote data acquisition systems with ease.
